	<p class="tip">
		<em>NOTE!</em>
		Set the <code>emptyTo</code> selector below:
		<ul>
			<li><code>top</code> - sort empty table cells to the top.</li>
			<li><code>bottom</code> - sort empty table cells to the bottom.</li>
			<li><code>none</code> or <code>zero</code> - sort empty table cells as if the cell has the value equal to zero.</li>
			<li>Individual columns can be modified by adding the following (they all do the same thing), set in order of priority:
				<ul>
					<li>jQuery data <code>data-empty="top"</code>.</li>
					<li>metadata <code>class="{ empty: 'top'}"</code>. This requires the metadata plugin.</li>
					<li>headers option <code>headers : { 0 : { empty : 'top' } }</code>.</li>
					<li>header class name <code>class="empty-top"</code>.</li>
					<li>Overall <code>emptyTo</code> option.</li>
				</ul>
			</li>
			<li><code>emptyToBottom</code> option was added in v2.1.11, then replaced by the <code>emptyTo</code> option in v2.1.16.</li>
		</ul>
	</p>

<h1>Demo</h1>

Set <code>emptyTo</code> option: <select>
	<option>bottom</option>
	<option>top</option>
	<option>zero</option>
</select>

* <strong>Note</strong>: The "Account #" column has the "empty-top" class name set which over-rides the <code>emptyTo</code> option (see the order of priority note above).
